The perfect location if you want to live like a local.
The apartment is great, it's right on the MRT line and the gym, pool, rooftop garden, coworking space and convenience store which are all on-site give you everything you need to live in a little bubble of productivity.
It's easy to get anywhere thanks to the MRT- but it does take a while because Bangkok is so huge.
If you're planning a long stay and you'll be working while you're there then Nui's place is perfect!
